TIMER.

Application filed-November 2, 1922. Serial No. 598,463.

Tof all whom t .may concern.'

Be it knownthatI, HoBART FREIBURG- ing at, Goff, .in the county ofNemaha land v'State of Kansas have invented certain new and usefulglmprovements 1n Timers, of

which the following isa specific-ation.

form otitimer `adapted for specific application to Ford automobilesforovercoming the necessity of providing the usual spark coil for eachcylinder, it being well known in this type of motor vehicle a spark coilis employed for each cylinder for building up the current between themagneto or battery and the contact points of the timer, insuring what isusually termed a hot spark.

A still further object of the present invention is the provision of sucha timer that is simple in operation and comparatively inexpensive ofmanufacture and a timer that when once installed is not liable toreadily become out of order` With the above and other objects in view asthe nature of the invention will be better understood by reference tothe accompanying drawings forming part of the present application, thesame consisist of the combination and arrangement of parts hereinaftermore fully described In the accompanying drawings, wherein likereference characters indicate corresponding parts throughout the severalviews:-

Figure 1 is a front elevational view of the timer casing clearlydisclosing the spaced contact points arranged therein, and also settingforth an additional contact point, centrally disposed within the timer,and constructed in accorda-nce with the present invention.

Figure 2 is a cross sectional view upon the line 2-2 of Figure 1.

Figure 3 is a View similar to Figure 2, but disclosing in addition tothis figure, the rotating contact arm positioned upon the usual rotaryshaft.

Figure 4 is a fragmentary side elevational view of the rotating contactmember, a. portion of the same being shown in cross section, disclosingits connection to the rotary shaft, and

Figure 5 is a diagrammatic view of the electrical Wiring system,employed by me in the vehicle frame.

vthe application of thepresent device to an l u Iinternal combustionjengine. lH oUsu, a citizen ot the United` States, resid- -Referring tothe several view, andparticularly to Figures/1 to 3 inclusive,` there isdisclosed atimer embodyingthe usual fiber casing 1'having a lining 2arranged ltherein. 'This casing 1 has the usual inter- The primalyobjectof the present invenl tion` resides inthe provison of an improved nalequi-distantly spaced contact point-s 3, each ot the samesecured withinthe casing by the post members 4, passing through suitableopenings inthe lining 2, and casing to Vbe theresecured by the binding nuts 5.

Centrally disposed within the` casing 1,

and'spaced inwardly of the rear wall thereof, is an annular shapedmetallic disk 6, this disk is rigidly positioned within the casing by ascrew threaded bolt member 7 formed upon the disk and extendingoutwardly of the casing as shown in Figures 2 and 3.

Extending within the casing as in the latter mentioned figure, is theouter end of the cam shaft 8, reduced and screw threaded at its extremeend portion 9 for screw threaded engagement within a screw threaded bore10, of a fiber block 11. Suitably secured to this fiber block is theusual metallic arm 12, carrying a roller contact 135 for engagement withspaced stationary contacts 3, within the casing 1 when the cam shaft 8is rotated.

Centrally supported upon the rear wall of the liber block 11, is ahorizontally extending relative sensitive helical spring 14, adapted tohave its free projecting end 14 contacting with the annular disk 6 ofthe casing 1 as clearly shown in Figure 3. Conveniently supported uponthe upper longitudinal surface of the liber block 11 is a flat-likemetallic arm 15 having its outer end 15 curved downwardly for contactwith one of the convolutes of the above mentioned coil spring 14. Thismetallic arm 15 may be secured to the fiber block by a set screw or thelike having a knurled annular head 16.

In the diagrammatic view, Figure 5, the stationary contact points 3 areshown as being electrically connected to the several spark plugs 17 ofan internal combustion engine by electric wires A, the said spark plugsbeing suitably grounded as at 18 to The flat-like contact disk 6 in thecasing 1 is connected through the instrumentality of the binding post 7,with one end of a high tension wire Z) from the single spark coil o,this coil also ""2 14e and metallic arm 15,.it will be readilyunderstood that the current from thehigh tension wire is carried by thespring le to the roller i3 which makes lContact with the stationarypoints 3, each of which is "f connectedto its appropriate plug 17. for

iii-ing these plugs in each cylinder at the predetermined time as is nowthe case With the conventional form of timer.

While the form ot the invention hereinshown and-described is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that various forms', modifications and arrangements of theparts may be made Without departing from the spirit and scope of theinvention as claimed.

VVhatI claim as new is A timer comprising a shell, a lining ofinsulating material located therein, a plurality. "of spaced contactspassing transversely through the shell and lining, a block mounted forrotation in the shell, a brush carried by the block for successiveengagement With the contacts, a. bar arranged Within the lining, abinding post connected with the bar and passing through the lining andshell, a coil spring interposed between the bar andthe bloeklandconnected with the bar, and a. conductor mounted upon the block andhaving an angularly disposed. end portion Which engages the convolutionof the coil springs.
